[ovs-dev] [PATCH] netdev-offload-dpdk : add ipv6 rte flow item support
From: Liu Chang
Nowadays some Nics support hw offloading via dpdk rte_flow lib.
Many layer2-layer4 fields can be offloaded to nics, including smac/dmac
ipv4 sip/dip etc. Also some nics(including intel X710) supports ipv6
header offloading, but when we execute netdev_offload_dpdk_add_flow,
there is no IPV6 rte_flow pattern.
This patch adds support for IPV6 header hw-offload rte_flow pattern,
including ipv6_label, nw_ttl, nw_proto, ipv6 sip and dip, also the
corresponding mask filed is added.
